Note for Bridge to the Divine perk for BAC Jump

-Generally speaking, you’re limited here to the kind of effects that a late Bronze Age or early Iron Age person would expect a priestly ritual to accomplish. Ensuring a good harvest for a land the size, maximally, of New Kingdom Egypt or the Middle Assyrian Empire? Perfectly fine. Cursing a man to die of a wasting illness, to suddenly drop dead, to be rendered impotent or even have a rat tear out his throat? All good. Getting a year of mostly favorable weather for your locale? Workable but a bit expensive. Divining limited details of future events? A good liver-reading away. You’ll note that pretty much all these things are, from our perspective, at least theoretically explainable as a product of natural phenomena, or random chance. Admittedly, invoking say, Indra, to send devastating floods to an oppositional country that happens to have major flood-prone rivers is effectively supernatural, but since it could be explained away as natural phenomena with your ritual being coincidence, it is permissible. Simply keep in mind that the greater the scale, the greater the complexity and material cost of the ritual/rite.

-Beyond that, the rites, rituals and prayers you use to accomplish these things have to have some basis in the religious tradition you’re following and the cultic practices of the particular deity in question. Fudging certain details and introducing limited innovation in form and style is within your purview as a priest, but there needs to be a solid basis in the tradition for what you’re doing: No begging Amun Ra to induce a nuclear fusion reaction in Mohenjo-daro or anything silly like that.

-If something is well-grounded in the specific, pre-existing practices of a faith that exists in this or future jumps that you have been to, comparable to the belief that Gilgamesh can be invoked to exorcize ghosts and demons, that Ishtar or Aphrodite can be invoked to curse men into women, or the Christian belief that the bread and wine of communion becomes the literal flesh and blood of Christ, then mild unquestionably supernatural effects can be brought forth.
